GAGAN Delayed Again

ISRO GSAT-4 satellite

India’s first GPS/SBAS payload, the GAGAN (GPS-Aided Geo-Augmented Navigation system) transmitter on the GSAT-4 geostationary satellite, disappeared into the Bay of Bengal on April 15 when its ill-fated GSLV-D3 launch vehicle veered off course.

The Indian Space Research Organization’s GSAT-4 satellite carried a communication payload of multi-beam Ka-band pipe and regenerative transponder and a navigation payload in C, L1 and L5 bands.

A key part of India’s GPS augmentation plan, the failure will further delay civil aviation modernization.

ISRO Chairman K. Radhakrishnan promised another launch within a year.
